Traffic rules and road signage for group T
The rules questions in the group T test are rarely about motorway cruising. They test the situations a tractor and its trailer actually meet: village streets, field entrances, narrow lanes, junctions where a long assembly cannot turn like a car. Expect sign recognition, priority, speed limits and the signs that exclude or specifically admit tractors.
Speed limits and where a tractor may go
- Built-up area (obec): 50 km/h. Outside a built-up area: 90 km/h. Motorway: 130 km/h; road for motor vehicles: 110 km/h. These are general ceilings; a tractor is always bound by the lower of the legal limit and the maximum construction speed recorded in its registration certificate.
- A passenger car towing a trailer is limited to 80 km/h outside built-up areas. Do not transfer that figure to a tractor: its construction speed (often 40 km/h or less) governs, and a heavy implement or trailer only lowers it further.
- Motorways and roads for motor vehicles are not intended for tractors. A round prohibition sign with a tractor symbol bans all tractors, including those carrying implements. A supplementary panel reading "Mimo dopravní obsluhu" (except local traffic) admits you only if your destination lies inside that zone; a shortcut to the next village does not qualify.
Priority and junctions
Czech traffic keeps right. At a junction with no signs, give way to vehicles coming from the right. The triangle sign (Dej přednost v jízdě) means give way without necessarily stopping; the octagon (Stůj, dej přednost v jízdě) requires a complete stop at the stop line. In a roundabout, give way to traffic already circulating and signal when leaving. Trams have priority over road vehicles, and you must never stop on a level crossing.
Worked example
You drive a tractor with a 3.5 m cultivator to a farm inside a village whose entry carries "Zákaz vjezdu traktorů" plus the panel "Mimo dopravní obsluhu". May you enter, and how fast? Reasoning: the panel admits vehicles whose destination is inside the restricted zone, so yes - the farm is your destination. You may not cross the village as a through route to reach a field on the far side. The built-up limit of 50 km/h applies, but your construction speed caps it lower. The implement is wider than the lane, so you must judge oncoming gaps and mark any part overhanging the vehicle.
Traps that cost marks
- Quoting 80 km/h for a tractor with trailer.
- Reading "Mimo dopravní obsluhu" as a general permit.
- Confusing the give-way triangle with the stop sign, or stopping where only giving way is required.
- Forgetting that a turning assembly swings wide and the trailer cuts the inside corner.
